University of Nebraska Kearney - Kearney, NE

Project Description:

The east and west campus areas of the University of Nebraska at Kearney were served by a central heating system originating from two plants, one constructed in the 1930s. Both plants housed boilers and one contained a chiller. The majority of the steam piping was routed through walk-through tunnels. Chilled water piping was routed through walk-through tunnels and was also direct buried. The new central plant houses 4-boilers and 2-chillers. The purpose of the project was to expand and enhance the central system to provide additional capacity and reliability. Some existing tunnels were replaced and more tunnels were added to distribute the Hydronic Piping throughout the campus. The new campus distribution piping was either routed through the existing / new tunnels or was direct buried. The new distribution system was installed alongside the old system in these tunnels as to facilitate little downtime or disruption to the campus. Some mentionable system components are:

-(2) 900 hp Superior Super Seminole 3-pass wetback boilers

-(1) 600 hp Superior Super Seminole 3-pass wetback boiler

-(1) Precision HVJ electrode boiler 9,900 Pounds Per Hour

-(1) BFS Tray Deaerator and Surge Tank

-(2) 1332 ton York centrifugal liquid chillers

-(4 ) Tower Tech Modular Fiberglass Cooling Towers

-(1) Puroflux Sand Filter, 475 gpm, 1425 gal capacity

-5,000 Lin. Ft of Campus distribution Piping

Army Reserve Center - Omaha, NE

Project Description

After many years of use, the Army decided to build a new state-of-the-art Training and Maintenance facility to replace the pre-World War II building in north Omaha. The facility consisting of a Training Building, and Operational Maintenance Building required the coordination of several trades to complete the project. The facility is described as an 800 soldier facility serving 14 units. An average drill weekend will support over 250 soldiers. To complete the project on time an aggressive schedule was developed to allow all trades to complete their work. Creative and innovative methods of prefabrication were adopted. Nearly fifty percent of the project was prefabricated so that when our allotted installation time came up on the schedule we were able to reduce the time allotted which helped the project to move along at a faster pace. Autocad coordination drawings were critical for the success of this project. All sub-contractors participated in this process so that at the time of construction everyone knew what location their work would be installed. The contract required a vehicle wash recycle system. This closed loop system was designed through the value engineering process and the use of cad drawings provided by Midlands Mechanical, Inc. An HVAC commissioning team was developed for the final phase of the project to verify the successful completion of the HVAC system. Some components of the pump house are:

• 1,000 gallon expansion tank
• Pre-water filter
• Water Softener
• Ultraviolet light filter

Offutt Fire Crash Rescue - Omaha, NE

Project Description

After many years of project budgeting, Offutt Air Force Base decided to build a new state-of-the-art Fire / Crash Rescue Station to replace the oldest and smallest station within the Air Force command throughout the world. The 48,000 square foot facility required the coordination of several trades to complete the project. To complete the project on time an aggressive schedule was developed to allow all trades to complete their work. Creative and innovative methods of prefabrication were adopted. Nearly fifty percent of the project was prefabricated so that when our allotted installation time came up on the schedule we were able to reduce the time allotted which helped the project to move along at a faster pace.

Autocad coordination drawings were critical for the success of this project. All sub-contractors participated in this process so that at the time of construction everyone knew what location their work would be installed. Seismic and Force Protection requirements were another hurdle for such items as ceilings, lights, HVAC equipment, pipe, and duct. Careful coordination of cable installation was critical to protect all contractors from being blocked away from completion of their work.

An HVAC commissioning team was developed for the final phase of the project. The task of this team was to verify that all equipment performed per the specification and at completion of the fourteen day Performance Verification test it was agreed that the HVAC system for this project was a success.

Regis Jesuit High School Performing Arts Center

Project Description:

New Performing Arts Center Building - Aurora, CO.

The project consists of Heating Water System with Condensing Boilers, (3) Rooftop Air Handling Units with Heating water coils and DX Cooling, VAV's with Reheat Coils, Heat Exchanger with 5 Snowmelt Manifolds serving (5) separate Areas. Plumbing for (2) major restroom groups, Drainage piping from the orchestra pit which required a depth of 16' to tie into main line. Domestic Water feeds from existing Boys School underground to the new Performing Arts Center. The structure is 40' high resulting in high piping runs which required working off scissor lifts for the majority of the areas of the building.

Regis University - Clarke Hall, Denver, CO

Project Description

This four story administrative building had multiple systems. Midlands Mechanical, Inc. did 3D coordination which greatly aided in the construction of this job. As with our other coordination jobs, the coordination model (in Navisworks) was used on site by our field guys to visualize what would be getting installed. We also installed Low Pressure Campus Steam and Condensate along with Chilled Water Supply and Return that was routed from the Campus Plant to new building. This was approximately 400’ from building to building, and 1,600’ of underground steel pipe with HDPE Jacket. The mechanical room housed large Plate and Frame and Shell and Tube Heat Exchangers, Solar Panel and Solar Energy Domestic Water Storage System. On the roof were (2) Alliance Air Products custom Air Handling Rooftop Units that were over 35’ long, 10’ wide, and over 10’ tall. We did design / assist with the snow melt and radiant heat loop layout along with a steam condensate vault and receiver.
